Two escaped prisoners, who fled Lleida prison in October 2001 with a plan months in the making, managed to activate all state security forces and keep the population on high alert. The Mossos d'Esquadra, a newly formed police force, faced criticism from other institutions questioning their inexperience. The criticism intensified as the escape became more complicated, and the strain and frustration began to take their toll on everyone involved. In their exhaustive investigation, the police uncovered the unusual relationship that developed between Prieto, an unscrupulous criminal, and Calatrava, an addicted, sensitive, and educated offender, whom he ended up protecting in prison from others and even from himself. The escape story delves into the web of admiration and dependence that had formed between them. Their relationship was so intense and passionate that it led to an unexpected outcome.
